Leaked photos and video of the first Nokia phone to be running Windows Phone 7 Mango seem to offer the best of both worlds: the impressive design of the N9 and a new OS that should be supported for years to come.

Nokia CEO Stephen Elop was showing this phone codenamed "Sea Ray" at a press event when his pleas for "no pictures please" and for recording devices to be put away were ignored (lucky for us), which is how these images and brief video became available.

"Sea Ray" has the same slim body with sharp edges, and curved Gorilla glass over the all-screen look of the N9. According to the Hungarian site Technet's English translation of the leaked materials:

The device itself is nearly identical to the just announced N9. Some difference, we can see: different LED placement on the back (but the same 8 megapixel Carl Zeiss lens) and a hardware button for the camera on the right.

If this "Sea Ray" turns out to be the real thing, then Nokia may finally have a hit on its hands.
